If you are looking for data for a 139 grain lrx from barnes, and can't find any data anywhere. However, you see load data from a powder company for a 140 grain lead-based bullet of some form, can you use the load data from the lead bullet for loading the lrx?
Thanks
I ran out of AR Comp (Alliant) a few years ago before COVID. Couldn't find any anywhere. Switched to W748. Still using it and seems to work just as well for .223 and 62 gr loads. Just had to start over with load development but that doesn't take more than a few range sessions using the same bullet.
I see 8 lbs of AR-C available now for almost $60/lb. W748 is $33/lb. Is AR Comp twice as good? If it is it isn't apparent to me. I'm still a yuge fan of American Select but I have plenty. Actually I don't expect to be buying anymore powder for a long, long time.
A telephone guy was in my basement awhile ago and was eyeballing my reloading setup. He said I see you're in for the long haul. He was a reloader also.

In the P-F basket of deplorables.
I wouldn't just substitute an all copper bullet in place of lead, and use lead data that way. Copper bullets, being less dense than lead, take up more case volume, and have a longer bearing surface than lead core bullets. Pressures could be vastly different. For sure, if you try lead data with a copper bullet, start low and work up. I would think the pressures should be lower, but internal ballistics doesn't always work they way you think.
I will look at different brand copper bullet data, and consider that for substitution. Say using Hornady or Nosler copper bullet data as s starting point for Barnes bullets of the same weight.

Beware of my temper, and the dog that I've found...
Alliant is also a major supplier of propellants for the military, and not just powder. My feeling is that they have been pressed more heavily than other manufacturers that are more focused only on smokeless powder. This is just my impression, though. I don't have any data to back this up.
